Leading screw 43 is rotated, and then drives print platform 42 to move, and in print procedure, print platform can at the uniform velocity rise.The control machine
Structure 3 is controlled using microprocessor, and controlling organization is connected with exposure mechanism 2, printing mechanism 3 and Sheng Ye mechanisms 4 respectively, for controlling
The action of each mechanism.In the present embodiment, the exposure mechanism 2 uses DLP projector, projecting apparatus exposure mouth to be located at material trough
51 lower sections, the purple light that DLP projector is projected solidifies for printing solution, using projector projects, with contrast higher,
Therefore hardening time is short, and printing effect is high.
The Sheng Ye mechanisms 5 include the roundel hopper 51 for holding printing solution, and for driving material trough 51
The drive component of rotation.As shown in Fig. 2 the bottom of the material trough 51 is fully transparent or the transparent base plate 511 in subregion,
Base plate 511 can use glass or other all-transparent materials.The uniform transparent liquid of a layer thickness is coated with the base plate 511
State film 512, the transparent liquid film 512 uses ionic liquid, and the ionic liquid density is more than 1.1g/cm3, and light transmittance is more than
85%, non-volatility, surface tension is small, immiscible with the printing solution such as photosensitive resin liquid.The thickness of transparent liquid film 512
Less than or equal to 2mm.Transparent liquid film 512 described in the present embodiment, density is more than water, in the low speed rotation of material trough 51,
Surface smoothness is very high, will not produce ripple, while ionic liquid can also make shape between printing solution 6 and liquid film 512
Into smooth interface, it is easy to both to separate.
As shown in Figure 3-4, the drive component includes turntable bearing 52, bearing fixed seat 53 and motor 54, described
Material trough 51 is fixedly mounted on turntable bearing 52, and the bearing fixed seat 53 is fixedly mounted on pedestal 1 by rotary base 55

To 4 ~ 10 times of speed of common 3D printer；
Step 3：Repeat step 2 prints the second layer, until printing terminates.
The time of the pause of print platform 42 and material trough 51 is general according to by the cross section of printed matter Products（Solidify aspect
Product）And depending on the hardening time of printing solution（General print platform pause 0.1S-1S, the material trough pause 0.2S-1S）.
When cured layer area is smaller, printing solution solidification is very fast, print platform 42 and material trough 51 are without pause, direct uniform motion
It is capable of achieving printing speed；But a period of time of pausing is needed when cured layer area is larger, printing solution solidification is slower, on the one hand
It is easy to printing solution to be back to the lower section of print platform 42, on the other hand leaves and takes hardening time to exposure mechanism 2.
In print procedure, material trough 51 can uniformly rotate for 3D printing device Sheng Ye mechanisms described in the present embodiment（Printing
Platform also can at the uniform velocity rise）, it is middle without other it is prolonged pause or perseveration, can save it is original account for 80% it is uncured
Time, printing effect is significantly increased, the speed of 4 ~ 10 times of common 3D printer can be reached；Using highdensity transparent liquid
State film 512, it is ensured that liquid film 512 will not produce ripple, while highdensity in rotation process because of centripetal force surface
Bright liquid film can also make to form smooth interface between printing solution and liquid film, be easy to both to separate.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
Appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
